"Союзники" (Allies) refers to the coalition of countries that opposed the Axis Powers during World War II. This group primarily included major powers such as the United States, Soviet Union, United Kingdom, and China. They worked together to defeat the aggressive expansion of Nazi Germany, Fascist Italy, and Imperial Japan. The cooperation among the Allies was crucial for military strategy and resource sharing. Key events, such as the D-Day invasion and the Yalta Conference, highlighted their collaboration. The efforts of the Allies ultimately led to the defeat of the Axis Powers and the end of the war in 1945.
